Bigotry and intolerance are fundamentally irrational and illogical, so the so-called "left-bias" of science is just science being itself.
Now the comments in this HN page and the reason.com article are completely ignoring that, and only considering everything through a political filter.
TIL science ignores sex differences in body strength and endurance, racial differences in average IQ, the Putnam study on diversity and social capital, racial differences in aggression and their link to violent crime, and studies on the effects (irreversible) puberty blockers have on kids, among other things.
You can dislike these results, you can tell me I'm a bigot for even bringing them up, but you cannot correctly dispute them on the grounds of scientific inquiry. The fact that Scientific American would even try, as they have now for years, tells you all you need to know about their attachment to reality.
